A fissure cavity is a type of tooth decay that develops in the grooves (fissures) on the chewing surfaces of your back teeth, specifically molars and premolars. These grooves are naturally occurring and can trap food particles and bacteria, leading to decay.
Understanding Fissure Cavities
- Location: Fissure cavities form on the top surfaces of your molars and premolars, in the deep pits and grooves where your teeth meet. These areas are difficult to clean effectively with a toothbrush, making them susceptible to decay.
- Development: The decay process begins when bacteria in plaque interact with sugars in food, producing acids that attack the tooth enamel. Over time, this acidic environment weakens the enamel, leading to a cavity.
- Progression: Fissure cavities can progress quickly, especially during the teenage years. Early detection and treatment are crucial to prevent further damage.
- Risk Factors: Poor oral hygiene, frequent consumption of sugary drinks and foods, and a genetic predisposition all increase the risk of fissure cavities.
The provided reference states that "Cavities form on the top part of your tooth's chewing surface". This directly describes the location of fissure cavities. It also notes that this type of decay "tends to start during the teenage years and progresses quickly," highlighting the age group most affected and the speed of progression.
